| | 992 | * '''Description:''' The variadic macro data library, or VMD for short, is a library of macros which provide important functionality for variadic macros as well as integrating variadic macros with the Boost preprocessor library ( Boost PP ). It integrates with Boost PP without changing the latter library in any way. |
| | 993 | |
| | 994 | The functionality of the library may be summed up as: |
| | 995 | |
| | 996 | 1. Providing the means to extract any single token from the comma-separated data which makes up variadic macro data, as well as to calculate the number of tokens. |
| | 997 | 2. Convert variadic macro data to and from Boost PP data types. |
| | 998 | 3. Enhance the tuple functionality of Boost PP by providing a means of calculating the size of a tuple as well as by providing equivalent macros to Boost PP tuple macros which do not require the size of the tuple to be explicitly passed. |
